Groth was the first winery we visited in the Napa Valley. A beautiful estate in Oakville. Tom poured for us and was gracious enough to walk us through the room they store the barrels of their reserve wine. It is $10.00 for the basic tasting and we liked the 2008 Sauvignon Blanc that was just released and for me, of course, the Cabernet. I have some of the cabs in my cellar as well and will buy some of the Sav Blanc for the summer (just $18.50 a bottle).
